Ok to make this crystal clear to you. Alternate angles of certain scenes were used for some still frames in the book, and they do not appear in the film. I can also tell that each image is a full frame image, not cropped to a widescreen image.
I have included samples of the alternate angles scanned from the book. This should be a good indication for you.
